SPECIFICATION forming part of Letters Patent No. 735,463, abet August 4, 1903.

Application filed May 5.1902. Serial No. 105,912. (No model.)

My invention relates to andpermits con-.

venient and expeditious reference to the various schedules on a time-table of a railroad or other transportation company and protects the sheet from mutilation and defacement by preventing contact with grease and other objectionable substances incidental to train-service. It is especially designed for the use of railroad-enginemen while on trains. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure I is a perspective view of the entire machine, showing an adjustable station-name plate M and partial-exposure time-table J. Fig. II is a perspective view of the machine as it appears partly open with roller in position on which is wound the time-table to its stationary and normal position as when not in actual use. Fig. III illustrates the roller removed from the jacket on which the timetable is to be wound. Fig. IV is a perspective view of the time-table sheet, showing the same being attached to the roller. Fig. Visa crosssection of Fig. IV.

The machine is constituted as follows:

A cylindrical jacket A, divided and hinged at the back, has a curved spring B fitted to one end of one section of jacket A, as shown in Fig. I, and has two adjustable station-name plates M fitted to the concave outside surface on each half of the jacket A in the manner shown in Fig. I.' The jacket is suitably shaped to inclose a hollow rotating cylinder called the roller, Fig. III, which is connected to one end of an internal spiral spring D, that is coiled around and the other end connected to the aXleE,which extends lengthwise through the center of the roller 0, projecting beyond the ends and having its end 'M will be the desired information.

fitting as journals into suitable sockets F F in the end sections of the'jacket, Fig. II. The roller 0 is provided with a small rod G, fitted to the groove H, as shown in Fig. IV. A small movable tube I has a slot lengthwise through its surface, which inoloses a rod S, that extends through it lengthwise. This tube and rod serve as an operatingmeans for the traveling end of the time-table.

To adjust the time-table to the roller 0, lap one end of the doubled sheet J around rod G once, insert rod and lap into groove H the full length of rod G, allowingthe free end of the sheet to protrude between the parallel edges of groove H, as partly indicated in Fig. IV. To adjust the opposite end of double sheet around the small rod is withdrawn from the, tube I, and said opposite end is lapped around the rod S in the same manner as is done with the roller 0, above mentioned. To place the time-table in jacket, wind the entire sheet around the roller G, place the latter inside of jacket A, as indicated in Fig.

II, allowing the margin Ito remain just outside and parallel with the front edges of the closed jacket. Afewturns of the small projecting crank end of the rod. E, acting on spring D and engaged by spring B to prevent unwinding, will apply the necessary tension for retaining and automatically winding time-table J. To consult the time-table, hold the jacket A in one hand, draw the timetable out by pulling on thumb-strap K with the other hand to the desired train-number at top of column. Thefigures next to and exactly opposite any station-name on plate By releasing the thumb-strap K the time-table returns automatically withinthe jacket by action of spring D inside roller. The jacket is held firmly fastened by a flat and punctured spring N on the end of one-half of jacket engaging a small pin 0 on the other half, Fig. II. An adjustable station-name plate M having a strip of flat spring metal P which. is attached to and projects above the upper portion of said plate, said' part P beingadapted to engage the teeth in a fiat ratchet-plate X, secured above the same.

To the best of my knowledge and belief I am the original and first inventor of the machine as set forth in the above specification for handling a railroad time-table by the rotary method, as substantially stated.

I claim- 1. In a railroad time-table, the combination with 'a sectional hinged casing, of a springroller having its axis journaled therein, and also provided with a longitudinal slot therein,

a rod having a detachable time-table thereon detachably secured in the slot and adapted to be movably Wound on the roller, a spring secured to the casing and detachably connected to the axis of the roller, and the timetable also having its outer marginal operat ing portion secured to a tube, substantially as specified.

2. In a railroad time-table, the combination PAUL SIMS BUTTERWORTH.
